LC Guides

Antimalarial Drugs by Chiral HPLCChirex HPLC columns offer superior tools to analyze and purify new medicines for use in the war against malaria. In this technical guide, simple and direct chiral HPLC methods for the resolution of racemic antimalarial drugs are described.

HPLC Column Care GuideEvery Phenomenex HPLC column is a precision product which, though delicate, will provide excellent performance, reproducibility and column lifetime if cared for properly. The information and recommendations contained in this manual are designed to guide you in the care and use of your column, but should not be considered absolute. Please follow the instructions herein to maximize column performance and lifetime. Should you have any questions, please contact your Phenomenex Technical Representative or local distributor.

HPLC Troubleshooting GuideA systematic approach to identifying the problem is the best approach to troubleshooting your HPLC system. This guide is organized by five major categories of symptoms to help you quickly identify the source of the problem(s) you are encountering: pressure abnormalities, leaks, problems with the chromatogram, injector problems, other problems detected by the senses of smell, sight, and sound.

Sample Preparation Selection and Users GuideSample preparation is crucial in achieving desired LC or GC analytical results. Sample matrix effects can result in an array of interferences which can lead to poor chromatography as well as instrumentation drawbacks, hindering your approach and goal for the analysis.

Industry Guides

Essential Guide for Biofuel AnalysisPhenomenex is dedicated to supporting the biofuel industry with cutting edge chromatographic tools and resources designed to enhance production, simplify alternative fuels analysis, and lower production costs.

Chromatography Guide for Environmental TestingIn recent years, there has been a rapid, worldwide increase in environmental testing. The sudden emergence of hybrid vehicles and the recent trend towards biofuels highlight the growing concern for environmental pollutants. As the focus on environmental contaminants and cleanup has increased, there is heightened demand for more sensitive analytical tests to measure the amount of pollutants in the environment. Since 1982, Phenomenex has been committed to developing a broad range of products that will help companies accurately and reliably identify and quantify these contaminants.

Improved Methods for Forensic Toxicology AnalysisThe screening and confirmation for drugs of abuse and their metabolites present many challenges in toxicological analysis. Searching for illegal drugs in complex matrices, such as urine and blood, can prove to be difficult because if present, they may be found at very low concentration levels. Direct analysis of these samples is often hampered by endogenous compounds in the biomatrix. These interferences are often in higher concentrations than that of the target analytes and thus may mask their presence.
